let x be lenghth of candles.

thicker one---- in 1 hr 1/6th will go.
thinner one--- in 1 hr 1/4th will go.

let he lit for n hrs.

so in n hrs thicker one  goes n/6.
and thinner one goes n/4.

so remainini length are x-n/6 and x-n/4.so x-n/6=2(x-n/4) 
implie n=3x. if x=1 n=3hrs.

as per data,
 thicker one can consume 1/6 in an hour
 smaller can consume 1/4 in an hour.
consider after an hour,
thicker one  consume 1/6 & remains 5/6.
shorter one consume 1/4 & remains 3/4.
AFTER 2 HOURS,
thicker one  consums 2/6 & remains 4/6.
shorter one consumes 2/4 & remns 2/4.
AFTER 3 HOURS,
thicker one consumes 3/6& remains 3/6.
shorter one consumes 3/4 & remains 1/4.
THIS CLEARLY MEANS THAT,

THICKER IS 50% OFORIGIONAL LENGTH.
&
THINNER ONE IS 25% OF ORIGIONAL LENGTH.

let L be the length of candles and t be the time(hrs) he 
litted the candles.

after t hrs the propotions of loss is same...

so..
for thicker 6-t/4-t  =(L-x/2)/(L-x/4)

then u get t as 2Hrs
